Abstract

La conveniencia se logra al realizar el procesamiento dependiendo de la capacidad de decodificación en el lado de la recepción. Se procesan los datos de imagen de ultra-alta definición con alta velocidad de recuadros para obtener los primeros datos de imagen para la adquisición de una imagen de alta definición con velocidad base de recuadros, los segundos datos de imagen para la adquisición de una imagen de alta definición con alta velocidad de recuadros al ser utilizados con los primeros datos de imagen, los terceros datos de imagen para la adquisición de una imagen de ultra-alta definición con velocidad base de recuadros al ser utilizados con los primeros datos de imagen, y los cuartos datos de imagen para la adquisición de una imagen de ultra-alta definición con alto velocidad de recuadros al ser utilizados con los primeros a terceros datos de imagen. Se transmite un contenedor que incluye un número predeterminado de flujos de video que incluye datos de imagen codificadas de los primeros a cuartos datos de imagen. La información se inserta en el contenedor, la información correspondiente a la información que se inserta en cada uno del número predeterminado de flujos de video y se asociada con los datos de imagen incluidos en los flujos de video.
